4 or 6 Voice preset version of the OB-Xa which looks like a cross between a Vox continental and a Korg Lambda.. Often seen as a source of Xa spares really due to the factory patches being stored on Eprom and only a 4-octave keyboard. at least the Oberhem Levers are there and you can put a Monosynth on the Orange Voxy top unlike the Xa or X. If they`d made it so you could dump sounds from an Xa it would be a real Gem!. Sounds as good as an Xa obviously, so if you like the presets it could be the bargain of the millenium
